N2  - "De verdwijn-machine" by Kees Valkenstein is a novel likely written in the mid-20th century. The story revolves around Professor Wells, who invents a mysterious machine capable of making objects invisible, stirring curiosity and skepticism among the public. As his device gains attention, a significant part of his invention disappears, leading him on a quest to reclaim it.  At the start of the novel, we are introduced to the aftermath of a world war as people return to normal life, with an emphasis on innovation. Professor Wells's invention is showcased, but it soon becomes a point of intrigue when half of it goes missing. We also meet the Bruggemans family, who are vacationing in the Veluwe and include a curious boy named Koen. While exploring the woods, Koen discovers a mysterious box containing the remains of the disappear machine, subsequently experiencing the astonishing effects of invisibility, both with objects and his interactions with his friend Piet. The opening sets up a blend of adventure and mystery surrounding the machine's capabilities and the adventures that will unfold. (This is an automatically generated summary.)
